Garden Row Covers

I was asked about my garden row covers.  

6 ft rebar cut in half to slip 6' 1/4 pvc onto.

Purchased Amazon

 83"x25' Agribon AG-19 Floating Row Crop Cover / Frost Blanket / Garden Fabric Plant Cover

Snap Clamp 1/2 Inch X 4 Inches Wide For 1/2 PVC Pipe White 10 per Bag

The fabric tore to easy. I'm looking for more of a nylon screen type.
